What you want to do is manual graphics editing with the extracted files to merge them correctly at correct positions.
Thank you aluigi to be interested in my problem.
Ravioli also allows to insert the jpeg images into the original file.
The problem is that it is very difficult when the image is complex to modify it if it is in several pieces.
What I would like to do is to group these different pieces of images correctly into a single jpeg in order to modify it. Then redivide in several images to insert them again in the original file with Ravioli.
